The wave of violence broke out as nearly 20,000 people left the Prudential Center after Saturday’s Red Hot Chili Peppers show.

About 10 to 15 teens attacked five people near Broad and Market streets, including a 23-year-old Pennsylvania man who suffered a fractured eye socket, police said. The suspects also took victims’ cell phones.

Police have since been looking over surveillance video to try to identify the suspects.

“I think that the taking of the cell phones was secondary. I think the main focus on it was to assault them,” Police Director Samuel DeMaio told WCBS 880’s Levon Putney. “It seems like it was done just for fun.”

DeMaio said it appears to be an “isolated incident” and said this is only the second time something has happened around the arena since it opened.

Prudential Center officials say they wish the victims a speedy recovery and praised the work of the Newark Police Department.
